I can't give this a full review yet but will come back in a few months if I can remember! I just added 500mL to my 25gal nano reef to see if I can get nitrate-reduction effect happening. The product (the little pebbles) fit really well into the caddies in the back chambers, and whatever I couldn't fit I have hanging in a mesh back in the return chamber. It's not messy, easy to rinse, and I see no negative effects from adding all 500mL at once. It will take a few more weeks or months in order to see any obvious outcomes! If anything I hope it increases bacterial stability and boosts biological filtration. Lower nitrates is bonus.
